    Doosan Infracore makes prototype battery pack

    Doosan Infracore has manufactured a prototype battery pack for use on electrically driven vehicles including construction, mining and agricultural machinery and expects the prototype to help accelerate its battery pack business and motorised product development.

    The battery pack, which Doosan calls Prototype No.1, has been developed in-house by the company and a statement from Doosan said it expects to achieve annual sales of more than $444m by 2030. It added that a battery pack is the final form of the battery system mounted on motorised machines. It is configured with control and protection systems, such as a battery module that bundles a certain number of batteries in cell units into a frame, a battery management system (BMS) and a cooling system.

    Doosan Infracore said its battery pack offers the advantage of a flexible design to meet unit voltage and capacity requirements by combining standardised cylindrical battery cells. Using the BMS, the standardised and shared design has been applied to enable battery pack configuration with up to 32 modules regardless of parallel or serial connection. The battery cell offers improved energy density and stability by using structural adhesive physically and wire bonding electrically.

    Doosan Infracore said it has been developing battery packs after completing a feasibility review of the electric powerpack business last year. Having developed the prototype, it plans to manufacture an initial 1.7t electric excavator product with the battery pack after testing it while mounted on actual equipment.

    The statement quoted a Doosan Infracore official as saying: “The battery pack can be mounted on all electrically driven vehicles, such as construction, mining and agricultural machines and golf carts. We have set an annual sales target of $444m or more in the battery pack business by 2030.”

    Previously, Doosan Infracore has developed a mild hybrid powertrain technology, a middle step between the internal combustion engine and the electric motor drive. The hybrid powertrain adds electric motors and batteries to the internal combustion engine to offer power ignition, improved fuel rating and output, and reduced carbon emissions.

    “We intend to become the leader in the global engine market by accelerating the development of hybrid powertrains and developing electrical drive technologies in this great paradigm shift in internal engines,” said Doosan Infracore CEO, Sohn Dong-yeon.
